概述:1) The engine temperature is too high 如果发动机温度过高,不仅会加速机油老化、变质,而且还容易使机油变薄,导致机油压力下降。
(1)发动机温度过高
(1) The engine temperature is too high
如果发动机温度过高,不仅会加速机油老化、变质,而且还容易使机油变薄,导致机油压力下降。
If the engine temperature is too high, it will not only accelerate the aging and deterioration of the oil, but also easily make the oil thinner, resulting in the decrease of oil pressure.
(2)缺乏机油
(2) Lack of oil
如果油量不足,就会减少油泵中的油量,导致油压下降,加重曲轴和轴承、缸套和活塞的磨损。
If the oil quantity is insufficient, the oil quantity in the oil pump will be reduced, resulting in the decrease of oil pressure and aggravating the wear of crankshaft and bearing, cylinder liner and piston.

(3)油泵停止运转或油泵缺油
(3) The oil pump stops running or the oil pump is short of oil
油泵的驱动齿轮与传动轴的固定销的裂纹或配合键断开,以及油泵吸油物与泵油齿轮卡住,会使油泵停止工作,油压也降至0。
If the driving gear of the oil pump is cracked or the matching key is disconnected from the fixed pin of the transmission shaft, and the oil absorbing substance of the oil pump is stuck with the oil pump gear, the oil pump will stop working and the oil pressure will drop to 0.
(4)曲轴与连杆轴承配合间隙过大
(4) The fit clearance between crankshaft and connecting rod bearing is too large
发动机长期使用后,曲轴与连杆轴承之间的配合间隙会逐渐增大,油压也会降低。
After long-term use of the engine, the clearance between crankshaft and connecting rod bearing will gradually increase, and the oil pressure will also decrease.
(5)油过滤器堵塞
(5) Oil filter blocked
当油被过滤器堵塞而不能流动时,过滤器底部的安全阀被提起,油不经过滤直接进入主油通道。如果安全阀的开启压力过高,当过滤器阻塞时,安全阀不能及时打开,所以油泵的压力增加,添加内部泄漏,和石油的供应在主油通道,导致机油压力下降。
When the oil is blocked by the filter and cannot flow, the safety valve at the bottom of the filter is lifted, and the oil directly enters the main oil channel without filtering. If the opening pressure of the safety valve is too high, when the filter is blocked, the safety valve can not be opened in time, so the pressure of the oil pump increases, adding internal leakage, and the oil supply is in the main oil channel, resulting in the decrease of oil pressure.
以上就是搅拌一体车油压过低的原因希望对您有所帮助。
The above is the reason why the oil pressure of mixer truck is too low. I hope it can help you.
